Strange thing happened today, playing with my plexi clone i decided to plug in my pedals. I have a one spot attached to a boss power supply. It sonly feeding three pedals.. however, when i plug them in and turn on the amp...no sound. I plug in straight, no problems. So i think maybe the power supply is fried? (even though the leds on the pedals indicate power) Well i tried a pedal that I know has a battery and same thing. It friggin acts like a standby switch or something??? very odd. Can't be the amp .. or can it? Very odd indeed. Possibly a fluke. I might go back later and give it a go but i found this very strange.
